When it comes to choosing a new boiler for your home or rental property there are many factors to consider before making the purchase and going ahead with the new boiler installation. One of the most important things to consider is the type of boiler you want and which is best suited to your property and central heating system.
Buying a new boiler can be a big and expensive decision. At Tailor-Made Property services we regularly install new boilers for our customers in Romsey, Southampton and surrounding areas. We have put together a guide to help you gain a clearer understanding of the different types of boiler available to help you make an informed decision when it comes to choosing and installing a new boiler in your home or rental property.
Condensing boilers are often seen as one of the most cost-effectiveand energy efficientboilers available, owing to the fact that they typically extract over 90% of the heat they generate from the fuel they burn. Condensing boilers extract heat from flue gases which would otherwise go to waste with a non-condensing boiler.
Condensing boilers have come a long way since they were first released. Early condensing boilers were seen to be unreliable, making them an unpopular choice with homeowners, but any teething problems they had have been addressed.
Under Government legislation,any new boiler installation in the UK from 2005 have to be condensing whether they are combi, system or conventional.
The advantages of installing a new condensing boiler include:
● They are over 90% energy efficient.
● Cost-effectivedue to lower energy bills and energy efficiency.
● Lower CO2 emissions makesthem more environmentally friendly
The disadvantages of installing a new condensing boiler include:
● Boiler and maintenance can be a little more expensive.
● Condensate pipe on the outside of the propertycan freeze and could cause damage to your system.
A combi or combination boiler is a type of condensing boiler, they are very efficient and compact in design making them ideal for smaller homes or when there is limited space. They are called combi boilers due to the fact they are able to act as both a water heater and a central heating unit.
Combi boilers are one of the most popular choices for homeowners when installing a new boiler, it is estimated that over half of domestic boiler installations each year in the UK are combi boiler installations.
Water is heated directly from the mains, meaning if you have a combi boiler you will not need a hot water storage cylinder or cold water tank. The heating method used by combi boilers makes them very energy efficient and cost-effectiveto run as water is heated when it is needed, not heated, stored and wasted if not used.
The advantages of installing a new combi boiler include:
● You only heat the water you need, when you need it, making them energy and cost efficient.
● Combi boilers can provide a good level of water pressure as long as you have an adequate level of mains pressure.
● Ideal for smaller homes owing to their compact design, less pipework and no need for water storage tanks.
● Easier and cheaper to install.
● Unlimited hot water on demand, no need to wait for it to heat up.
The disadvantages of installing a new combi boiler include:
● Requires a good level of mains pressure.
● Not compatible with power showers as the pressure is dictated by the mains supply.
● Can’t use hot water in multiple rooms at the same time, such as running a bath while someone is in the shower.
● If your combi boiler breaks you will not have a backup supply of hot water in your storage tank.
A system boiler works in a similar way to a regular boiler, it directly heats your central heating and heats water to be stored in your hot water storage cylinder. While a hot water storage tank is required a cold water tank is not, making system boilers a suitable choice for smaller homes. System boilers include additional units within the boiler such as an expansion vessel and a pressure release valve.
The advantages of installing a new system boiler include:
● Easier to install than other types of boiler.
● Use multiple taps at once without a drop in water pressure or temperature.
● Cold water tank not required.
● System boilers are compatible with solar thermal systems to use the suns energy to heat water for your home.
The disadvantages of installing a new system boiler include:
● Not as compact as other boilers.
● Hot water tank heat loss.
● Hot water not on demand.
● Only as much hot water as your hot water tank can store.
A conventional or regular boiler system is made up of several parts such as a boiler, heating controls and hot and cold water storage tanks, making them less attractive for smaller homes. They are fed by two tanks which are usually located in the loft, the cold water tank draws water from the mains supply. While the feed and expansion tank feeds the boiler system and manages water expansion in the system after it has been heated.
The advantages of installing a new conventional boiler include:
● Use multiple taps at the same time.
● Suitable when replacing an older system as it requires minimal changes to pipework.
● Can be compatible with a backup immersion heater.
● Compatible with solar thermal systems.
The disadvantages of installing a new conventional boiler include:
● Needs a lot of space.
● Hot water tank heat loss.
● Hot water not on demand.
● Can be more complicated to install.
As the most common heating fuel type in the UK, many homeowners who have access to gas choose a gas boiler. Gas boilers are available as conventional, combi and system boilers and as of 2005,any new gas boiler installation must be a condensing boiler to meet legislation.
The advantages of installing a new gas boiler include:
● Cost effective to run compared to electric boilers.
● Gas is the cleanest fossil fuel creating less CO2 emissions than oil or coal.
The disadvantages of installing a new gas boiler include:
● You need to be connected to the gas grid, if not it can be costly to have your property connected.
Electric boilers are great for homes that are restricted by space or those who cannot be connected to the gas grid. Water is heated by a heating element and then pumped to where it is needed. There is minimal heat loss with electric boilers.
The advantages of installing a new electric boiler include:
● Can run at 99% efficiency.
● Uses simple technology.
● Compact design.
● Often cheaper to install an electric boiler.
● Doesn’t need a gassupply.
The disadvantages of installing a new electric boiler include:
● Can be expensive to run due to the highcost of electricity.
● May not be suitable for larger properties as only small quantities of water can be heated at a time.
● Heating and water system would be affected bypower outages.
Oil fired boiler systems work in the same way as gas boilers, but they are fueled by oil rather than gas. Oil fired boilers are an alternative when there is no gas supply to your property, but they may be more expensive to run and maintain.
The advantages of installing a new oil fired boiler include:
● Doesn’t need a gassupply.
● Could be cheaper to run than other types of boiler, such as electric boilers.
The disadvantages of installing a new oil fired boiler include:
● Running out of oil, oil levels need to be monitored to ensure you have enough.
● You may need to pay for oil in bulk rather than monthly.
● Oil tanks require a great deal of storage space.
